RUBBER-TlRE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 697,056, dated April 8,1902.

Application filed October 14, 1901. Serial No. 78,824. (No model.)

To aZZ whom, it may concern: 1

Be it known that 1, JOHN K. WILLIAMS, a citizen of the UnitedStatesn'esidin g at Akron, in the county of Summit and State of Ohio,have invented a certain new and useful Improvement inRubber-Tire-Setting Machines, of which the following is a specification.

My invention has relation to improvements in machines for lacin orsettin solid.

rubber vehicle-tires in channeled metallic tires.

The object of my invention is to produce a new and improved machine ofthe class named in which the line of draft of the wires shall be betweenthe clamping-arms and which shall be simple in construction, efficientin operation, and in which the number of parts shall be reduced to aminimum.

To the aforesaid object my invention consists in the peculiar and novelconstruction, arrangement, and combination of parts hereinafterdescribed, and then specifically pointed out in the claims, referencebeing had to the accompanying drawings, forming a part of thisspecification.

In the accompanying drawings, in which similar reference-numeralsindicate like parts in the different figures, Figure 1 is a frontelevation; Fig. 2, a section at the line 00; Fig. 3, a section at theline y; Fig. 4, a rear elevation; Fig. 5, a section at the line a, andFig.

. 6 a view of the winding-crank and pinion.

7 Referring to the figures, 1 is a metallic casting of the general formshown, being a plate with a lateral extension to permit of its beingbolted for support to a post 2. In the lower edge is anupwardly-extended curved notch 3, for a purpose to be stated, from oneside of which depends an arm 4, from the front face of which extends anintegral horizontal foot 5, having near its outer end a screw-threadedopening in which runs a screw 6, provided at its lower end with ahand-wheel 7, by which it may be turned, and at the top a freelymountedcap 8, having a curved top to adj ustably support a wheel-felly 9 duringthe process of setting the rubber tire.

The cap 8 has a rearwardly-projecting blade 10, the outer end of whichruns freely in a vertical channel 11 in the arm 4,and thus holds the capagainst turning with the screw.

In the lower front face of the plate 1, on opposite sides of the notch3, are pivots 12 13, screw-threaded at the outer ends, on which arefreely mounted the wire-clamps 14, between which extends aconnecting-bar 15, the

ends of which are perforated and fit on the pivots 12 13 and areretained by the nuts 16 17.

Each wire-cla1np consists of an inner bar 18, that rests against theplate 1, and an outer jaw 19, having pivotally mounted in a notch in itsupper end a handle-cam 20, arranged to bear against the bar 18 and whenthe handle of the cam is rocked down to force the lower end of the jaw19 toward the lower end of the bar 18.

Between the lower ends of the bar 18 and jaw 19 and supported by thepivot 12 or 13 is an intermediate plate 21 of like width.

The outer lower ends of the bar 18 and jaw 19 are reduced toward theirinner faces, and the adjacent faces of these parts and the plate havecorresponding oppositely-disposed grooves to grasp the tire-wires.

To the upper ends of each of the bars 18 is pivotally connected one endof a flat link bar 22, their opposite ends being freely mounted on ascrew 23, having a hand-wheel which passes through a slot 24 in theplate 1 and en ters a nut 25 at the back of the plate 1.

By raising or lowering the screw 23 in the slot 24 the wire-clamps canbe brought pew pendicular to the tangent of the wheel-rim and locked atany desired point, thus adapting the machineto wheels of differentdian1- eter.

Through the plate 1 are bored two holes to receive winding-shafts 26 27,having bosses at each end.

Back of the plate 1 0n the shafts 26 27 are splined-like gear-wheels 2829, respectively, provided with pawls 3O 31, respectively. The shafts 2627 are free to slide lengthwise in their openings and are held until itis desired to draw them backward by a plate 32, retained to thepivot-shaft of the pawl 29 by a set screw 33.

In the front end of each shaft 26 27 is a notch like those in ascrew-head, in which to place the wires for winding.

In the back of the plate 1 are three like socket-holes, the upper andlower, 34 and 35, respectively, shown in Fig. 4, the central one beingobscured by the pinion. Each hole has bosses at the rear of the plate togive additional bearing length, similar to those about the holes for theshafts 26 27. A shaft 36 is fitted to accurately enter these holes andhas at its outer end a crank arm and handle and bears a pinion 37,adapted to mesh in the gears 28 29.

In operation the rubber tire 38, with the wires 39 4O inclosed, isplaced about the wheel in the channeled metallic tire and secured at oneend in the right wire-clamp 14. The opposite ends of the wires are thenbrought between the members of the left wire-clamp 14 and the end ofone, 39, placed in the notchin the shaft 27, and the other is broughtunder the shaft 27 and up into the notch in the shaft 26. Thecrank-shaft is then placed in one of the holes 34 35, and for thepurpose of illustration it will be assumed in 34, and the wheel 28 andshaft 26 turned, winding the wire on the front end of the shaft until itis tight. The operation is then repeated with the wheel 29 until thewire 39 is drawn correspondingly tight by the shaft 27, the gears 28 29being held by the pawls 3O 31. The crank-shaft 36 is then placed in theintermediate socket-hole, with the pinion 3'7 meshing in both gears 2829 and turned simultaneously,

winding the wires on both shafts 26 27 until the required tension issecured. In this operation the wire coils close to the boss on the faceof the plate 1 in a spiral, forcing or drawing the shaft on which it iswinding to the front, and thus always causing the wire to draw in thesame relative position. The left wire-clamp 14 is then tightened on thewires and the wires out between the clamps 14 at suitable distances forforming a joint, the notch 3 permitting a file or like tool to pass forthat purpose. The shafts 26 27 are then pushed into the plate 1 untiltheir ends are flush with the face of the bosses, thus removing them outof the way of the workman in making the joint and stripping the coiledwire off from the shafts. The ends of the wires are then brazedtogether, the clamps 14 released, and the wheel removed to have the endsof the rubber brought together in any approved manner.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-- I 1.
